I want to execute a query in one file, store it in a session variable, and access the result in another file.

File1.php:

//This is the file I have executed my sql statement in

//I have already done session_start(); and initialized $conn

$query = //my query. I know it is working because I have tested it elsewhere, so I

// don't believe it is the problem

$_SESSION['query2'] = mysqli_query($conn, $query)

File2.php:

//This is the file I want to access my query results in.

//I have already done session_start(); and initialized $conn

$tempArray = $_SESSION['query2'];

if (isset($tempArray)) {

$row = mysqli_fetch_array($tempArray, MYSQL_NUM);

if ($row == null) {

echo "

error

} else {

echo "

works!

}

} else {

echo "

array not set

}

Any ideas as to what I am doing wrong? Or, is there another way to accomplish what I'm trying to do here?

Store the actual array in session:

File1.php:

$query = //my query.

$result = array();

$res = mysqli_query($conn, $query);

while($row = mysqli_fetch_array($res, MYSQL_NUM){

$result[] = $row;

}

$_SESSION['query2'] = $result;

File2.php:

//I have already done session_start(); and initialized $conn

$tempArray = $_SESSION['query2'];

var_dump($tempArray);
